Consider removing unused tags from jsdoc config

We have some legacy jsduck tags that are not recognised by jsdoc still available. These will be ingored by jsdoc so only exist for humans to read:

• cfg (should be an alias of param probably, but I don't think multiple aliases are allowed?)
• chainable
• constructor
• inheritable (does jsdoc assume all static props are inheritable?
• localdoc (does jsdoc inheritdoc already show local documentation?)
• singleton (jsduck warned when singleton's contained static methods. Replace with hideconstructor ?)
• uses

Longer list from #597:

* @accessor
* @alternateClassName
* @aside
* @cfg
* @docauthor
* @evented
* @experimental
* @ftype
* @hide
* @img
* @inheritable
* @localdoc
* @markdown
* @mixins
* @new
* @preventable
* @ptype
* @removed
* @singleton
* @template
* @uses
* @video
* @xtype

I would keep @constructor. 1) It is a valid JSDoc tag (it's a synonym of @class), and 2) some folks like to use this tag even when there's already a @class tag as they like to make it really obvious which method is the constructor. Example:
